measurements to a host receiver up to 450 m (1500') line of sight (LOS) away.

The UWXL transmitters are designed for a variety of applications, including

temperature (RTD or thermocouple), infrared temperature, relative humidity,

process transducers with standard voltage or current outputs, flow (pulsed

frequency) as well as pH measurement. When activated, the transmitter will

send readings continuously at a pre-set time interval programmed by the user

during initial setup. Each unit measures and transmits: Process value, Ambient

Temperature, RF Signal Strength and Battery Condition to the host. This

information is then displayed on the host PC screen in real time using the

provided software. When used with host receiver model UWXL-REC1, data

from up to 48 wireless end devices can be received and displayed

simultaneously. Each receiver includes free software that converts your PC into a

strip chart recorder or data logger allowing readings to be saved and later

printed or exported to a spread sheet file.accepts a Pt100 RTD probe (mating

Section 3 – Setup & Installation

3.1 Setup and Configuration

3.1.1 Connecting your device

Connect the USB cable to your transmitter unit and also to an available USB port

on your computer. See figure below. The USB cable is provided in the box with

your receiver unit. The same cable is used for programming your transmitter

and for connecting your receiver.

Figure 3-1. USB Cable

3.1.2 Configure Your End Device

Now that you have connected your USB cable to your PC and transmitter, you

will complete the following steps to configure your End Device before placing

the unit into operation. You will be using the configuration software utility that

you installed onto your PC when you set up your receiver. If you have not

installed the configuration software utility you should do so now. During this

procedure you will be setting the following parameters in your transmitter.

Transmitter Options:

Connector Address

This sets a unique address number into your transmitter. Later, when you set up

your measurement software you will again set channel numbers to receive

readings from the corresponding unit(s). Each end device must be given a

different address for your system to operate correctly

If you will be using more than one receiver unit in your area it

is important to set the transmitter address numbers to be a

corresponding number in your TC-Central software.

Example

For the first receiver: Set the addresses on your transmitters to 101, 102, 103, 104,

etc.

Then set the channels in your TC-Central user software to match.

For the second receiver: Set the addresses on your transmitters to 201, 202, 203,

204, etc.

Then set the channels in your TC-Central user software to match.

NOTE:

Setup & Installation

This numbering scheme can be expanded to match the number of receivers you

are using.

Sample Rate

This will program your End Device to transmit 1 data reading to your receiver at

a specified time interval. Available settings are 2, 3, 5, 15, 30, 45, 60, 75 or 90

seconds

The sample rate you set will have the most direct effect on the

life of the battery in your End Device. It is recommended that

you set the longest sample time that your application can live

with to extend time between battery replacements. See

Section 4 for more information on battery life.

RF Network Settings:

RF Channel

This setting determines the operating channel on which RF connections are

made between the transmitter and receiver. The transmitter must be set to the

same channel as the receiver in order for them to communicate.

Network ID

This sets the ID of the Network that the transmitter will be joining. It must

match the setting of the receiver in order for them to communicate.

Receiver Address

This sets the destination address for RF packets sent by the transmitter. It must

match the address of the receiver in order for them to communicate.

It is possible to have multiple RF networks operating in the

same vicinity. Each network must have at least one unique RF

Network Setting in order to differentiate the networks.

STEP 1. Enter the “SETUP” mode.

To place your transmitter into the SETUP mode for programming follow this

procedure.

3.2 Mounting, Installation and Antenna Connection

Your device has been shipped to you with a standard antenna already attached.

In some cases the user may wish to install a remote antenna to maximize

transmission range to the receiver. In these instances the UWXL-RAK kit can be

used. The kit includes a direction antenna, 8" extension cable and mounting

bracket.

3.2.1 Mounting

The diagram below shows dimensions of the transmitter housing for mounting.

Figure 3-11. Mounting Dimensions

When mounting your end device, care should be taken to make sure it is as far

away from any metal objects. If nearby metal gets too close to your unit, it has

the potential to interfere with the way the unit radiates and may cause signal

lose or possibly even the inability to communicate at all with your receiver.

3.2.2 Installation

When installing your End Device it is important to position your device in such

a way as to optimize the antenna location within what’s known as the “Fresnel

Zone”.

The Fresnel Zone can be thought of as a football-shaped invisible tunnel between

two locations that provides a path for RF signals between your End Device and

your receiver.

Transmitter Setup & Installation

3-9

Figure 3-12. Fresnel Zone

In order to achieve maximum range, the football-shaped path in which radio

waves travel must be free of all obstructions. Obstacles in the path (especially

metal) will decrease the communication range between your End Device and

receiver. Also, If the antennas are mounted just barely off the ground, over half

of the Fresnel zone ends up being obstructed by the earth resulting in significant

reduction in range. To avoid this problem, the antennas should be mounted high

enough off of the ground so that the earth does not interfere with the central

diameter of the Fresnel zone.

It is important to understand that the environment may

change over time due to new equipment or machinery being

installed, building construction, etc. If new obstacles exist

between your End Device and receiver, the devices can be

raised on one end or on both ends to hopefully clear the

Fresnel Zone of obstructions.

No co-location with other radio transmitters is allowed. By

definition, co-location is when another radio device or the

device’s antenna is located within 20 cm of your connector/

transmitter and can transmit simultaneously with your unit.

RECEIVER ANTENNA

TRANSMITTER ANTENNA

NOTE:

Never install multiple End Devices within 20 cm or less from

each other.

Never use your UWXL End Device as a portable device. Your

unit has been designed to be operated in a permanent

installation only.

3.2.3 Antenna Connection

Your End Device has been shipped to you with a standard antenna already

attached. In some cases the user may wish to install a remote antenna to

maximize transmission range to the receiver. In these instance the UWXL-RAK

antenna kit can be used. The kit includes a direction antenna, 8” extension cable

and a mounting bracket.

In some cases, a short RF cable may be used to connect an antenna to your device.

Please note that RF extension cables will always add some loss to the transmitting

signal strength. The longer the cable the more signal will be lost over that cable.

Because of this the length of the cable should be kept as short as possible.

Use of any other antenna then what’s supplied with your End

Device will void all FCC, and IC regulatory compliance.

Additional information on installation and system operation can be found in

Section 4.

3.3 pH Probe/RTD Connection

Your transmitter features a standard BNC receptacle allowing most pH probes

with a BNC connector to be used. For automatic temperature compensation

there is a M12 connection for an RTD probe. Each transmitter comes with a field

wireable mating connector for easy connection to any RTD with stripped leads.

3.4 Battery Replacement

3.4.1 Model UWXL-24-PH

To install or replace the battery in your End Device you must first remove Lid of

the enclosure. This will allow you to access the battery compartment.
